Leicester City boss Enzo Maresca made a winning return to The Hawthorns as the Foxes left it late to beat his old club West Bromwich Albion.
Midfielder Kiernan Dewsbury-Hall put the Foxes in front with a 71st-minute header from Wilfred Ndidi's right-wing cross.
Josh Maja's 89th-minute scrambled equaliser looked to have earned the hosts a point - his first goal for the Baggies.
But, with Albion chasing a winner, four minutes into added time, Dewsbury-Hall raced clear down the inside-left channel on a counter-attack before squaring for Harry Winks to slide home just inside the right post, securing a welcome victory after a run of just one win in four games.
